I've been searching this topic extensively here on yotatech and have not found much comments from people with T100's.
I think i saw on or two people that chimed in and simply said brembo blank rotors....

I am in need of an upgrade soon (and am just tired of poor braking---is this common with the t100's?) so i am wondering what you guys think.

I've looked at blanks and drilled, slotted, or a combination of drilled and slotted. from a variety of companies.
Brembo--we all know and respect
Powerslot--seems pricey but might be worth it
ATE--unsure as to this brand
and others

for pads ive lookd at Axxis, Hawk, OEM, Satisfied, ATE, and many more

but i'm unsure as to which perform well with this truck.

i want good breaking performanc for a reasonable price. i would be happy with 200 for pads and rotors (front only) but would be willing to go 300 or slightly more for the right set-up.

Also, has anyone done a (or is there one even available) rear brake upgrade to disc brakes???

any knowledge on the supject would be great

 

Check out Front Range Off Road for the disc brake conversion. It's not cheap. Google their website.

 

I just replaced my brakes and rotors, I got both of them tirerack.com. Cost me 185 with shipping.

Got Hawk LTS pads and brembo blanks, before that I had yota OEM gear. Its highly improved, very noticable and I feel much better on road.
